Heading into the fantasy baseball draft season, everyone spends a considerable amount of time tracking down sleepers -- particularly those young, relatively under-the-radar players set for more playing time or coming off strong finishes to the previous season.

There are several different "types" of players that can be considered sleepers, though. One such example is the veteran player coming off a poor campaign, a.k.a "comeback player." Whether due to injuries or mechanical flaws, even the game's best can struggle for a season, setting up savvy and/or forgiving fantasy owners to turn a profit when these guys bounce back the following year.

Here is a look at the Fantasy Source experts' preseason picks for Comeback Player:

Williams' pick: Matt Kemp. The hamstring issues are a concern, but an even bigger concern was the shoulder surgery that Kemp underwent last offseason. A year removed from that operation should allow him to get his power back to the levels that fantasy owners have come to expect. Prior to 2012, Kemp could be penciled in for 600 at bats, and at 29, there is still a chance for him to avoid the "injury-prone" tag that he is ever so close to earning.

Bender's pick: Nelson Cruz. Cruz got hit with a 50-game PED suspension and remains unsigned as of now. He's 33 years old, so his best days are likely behind him, but that doesn't mean he's done as a fantasy contributor. And while PEDs may help players, they don't provide raw talent.

Lutovsky's pick: B.J. Upton. Melvin, Upton's real name and the one we use around the office when he performs like he did in 2013, can't get any worse than his .184/.268/.289 triple-slash -- at least we hope. Perhaps getting a year under his belt in Atlanta and the NL will allow him to bounce back in 2014. The fact that he's still "just" 29 and possesses the tools to be a fantasy stud will likely get him drafted, but fantasy owners certainly won't give him a very long leash.

Pinkerton's pick: Justin Verlander. This was a safe bet before Verlander had to undergo core muscle surgery, clouding his status for the start of the season. Assuming he's back to 100 percent at some point in April, one has to believe that he can erase last year's "down" season. Verlander was dominant in Sept/Oct (39.2 IP, 2.27 ERA, 10.9 K/9) and in the postseason (23 IP, 0.39 ERA, 12.1 K/9) so he's not done being an elite hurler yet. Just keep an eye on his recovery ahead of your drafts.

Valentine's pick: Dan Haren. Haren struggled through 2012 and followed that with an even worse performance last season. His home run rates have been troublesome (1.43 HR/9 in 2012; 1.49 in 2013), but playing home games in Dodger Stadium this season could help him get back on the right track. It's worth noting that Angel Stadium and Nationals Park aren't exactly hitter's parks, but Valentine likes the chances of Haren delivering solid value to faithful fantasy owners willing to trust the advanced stats (8.0 K/9, 3.67 xFIP).
